What Does that Light Mean? Top Diagnostic Gadgets for Your Car

Automatic™ Link ($99.95) The most affordable option on the market, the Automatic Link works on most gasoline engine

vehicles sold in the U.S. since 1996. Simply plug it into the port near the

steering wheel, and you’ll have access to your engine’s computer through your smartphone. The Automatic Link deciphers the code when your vehicle’s check engine light goes on, and may turn off the light if the problem is something simple. If it turns out to be something more serious, the app will give you a list of nearby reputable mechanics. Additionally, it’ll remind you where you parked, track your gas mileage and notify the authorities if you get into an accident. Visit automatic.com for more information.

2. Check your fluids and tire pressure. Once a month or so, take a minute to open up the hood and check your fluids, including the oil, power steering fluid, etc. With the exception of the oil, you can see how much fluid you have with just a look at their respective reservoirs.

4. Watch your driving. Sudden stops and starts can take a toll on your engine and cause the components to wear out sooner than expected. Go easy on the gas and brake pedals and you’ll keep your engine humming and may even improve your fuel economy as well.

5. Take care of your car. A thorough cleaning, followed by wax, does more than make your car shine like new. It protects the paint by eliminating the dirt and grime that accumulates when you drive. Don’t forget to vacuum and dust the inside of your car as well.
